Let's divide 878733 by 45
We're looking to find how many times 45 goes into 878733.

Going ahead to step 1:
If we divide 8 by 45, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 45

Going ahead to step 2:
45 can be fit into 87 1 times, resulting in a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 87, we get 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 45

Step 3:
When dividing 428 by 45, we get 9 with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 405 away from 428, we end up with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 45

Let's proceed to step 4:
The number 45 fits into 237 5 times, leaving a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 195.0
Deduct 225 from 237 and we're left with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 45

Going ahead to step 5:
If we divide 123 by 45, we get 2 and a remainder of 33.
The next digit of our result is 2. 
Result so far: 1952.0
If we take 90 away from 123, we end up with 33.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 45

Let's proceed to step 6:
The number 45 fits into 333 7 times, leaving a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 19527.0
If we subtract 315 from 333, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
180 divided by 45 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 19527.4
The remainder is 0 after subtracting 180 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19527.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 45 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19527.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 19527.4 with a remainder of 0.0.
